Best way to cool your iMac
Authored by: fgduncan on Aug 31, '13 03:48:59PM

24 inch iMac Early 2008

My iMac had always had a hot upper left corner, as I have found all iMacs do. Recently I had started having the computer reboot in the middle of a job and the corner was so hot that you felt uncomfortable touching it.

This worked absolutely fantastic!! Downloaded the fan controls and adjusted them as recommended and 5 minutes later the computer was very much cooler and temps are even lower than those shown. Downloaded istat nano and now have an instant check on the temperatures, although I obviously do not need that anymore.

I was amazed to find out that not only were there fans inside the iMac, but that the computer knew exactly what their speed was and, in addition, could control them. Another surprise came when I found that the computer has temperature measuring devices inside of it.

I would highly recommend following the directions given here since applying external cooling to an internal problem is not fixing the problem at the source. These two programs are free and easy to use, so using external cooling is a waste of time and money.

The only complaint I have is istat nano is in degrees C and not degrees Fahrenheit, but I can learn to live with that.

Mega kudos to the author!!
